The java::null command takes no arguments and returns an object handle that represents the "null" value in Java. This command is typically used to get a "null" handle that will be passed to a Java method. The exact form of the return value of java::null is not specified and is likely to change but this should be of little concern as you should not need to know what the string representation of the "null" Java object is. If you ever need to test a handle to see if reffers to the "null" Java object you should use the java::isnull command.
